Abstract

Simulating a physical process [Fig. 3, item 302] includes storing, in a computer-accessible memory, state vectors for voxels, where the state vectors correspond to a model and include entries that correspond to particular momentum states of possible momentum states at a voxel. Interaction operations are performed on the state vectors. The interaction operations model interactions between elements of different momentum states according to the model. Move operations performed on the state vectors reflect movement of elements t new voxels according to the model [Fig. 3, items 310, 314; Fig. 13, items 1318, 1338, 1340]. The model is adapted to simulate a high-Knudsen number flow that has a Knudsen number greater than O. 1.
